Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.

The Museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Other artifacts range from personal computers to ENIAC, the Altair, and the Osborne 1. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

This Ethernet board is a prototype developed by Robert Metcalf in 1973 while at Xerox Palo Alto Research Center (PARC). Metcalf based his idea for the Ethernet on the ALOHAnet, a packet-switching wireless radio network developed by Norman Abramson, Frank Kuo, and Richard Binder at the University of Hawaii-Manoa. The ALOHAnet sent computer data communication between the university's campuses on several islands. Metcalf improved upon ALOHAnet's design and created the "Alto ALOHA Network," a network of computers hard-wired together by cables that he soon called the Ethernet. In 1985, the Ethernet became the

This Black Apple, model number A2S1048B, was a version of the Apple II Plus made by Apple Computer, Inc. and sold only to educational institutions by Bell & Howell, at that time a company specializing in audiovisual equipment. It earned the nicknames "Black Apple" and "Darth Vader" because its case was black instead of the usual beige color of the Apple II Plus. To make the computer more versatile, Bell & Howell added audio and video slots onto the Apple II Plus and also made it UL-compliant. By allowing Bell & Howell to sell their modified product, Apple was able to succeed in the educational market.

In 1975, Steve Wozniak designed the Apple I as his personal computer to use the ARPANET and play games. Its enthusiastic reception among the members of Silicon Valley’s Homebrew Computer Club prompted Wozniak and Steve Jobs to form Apple Computers to manufacture the Apple I. Wozniak designed the Apple I around two principles; making the machine affordable by minimizing the number of chips; and the ability to output video to a TV screen most users already owned. With the incorporation of the microprocessor and dynamic RAM, the Apple I proved how small, simple, and cheap a usable computer could be.

The computer sold as a single board for $666.66 since Wozniak liked repeating digits. To complete the setup the board required a video display monitor, an ASCII encoded keyboard, and an AC connected power unit supplying 8 volts at 3 amps and 28 volts at 1 amp. Aside from the 6502 microprocessor running at 1.023 MHz, the Apple included four kilobytes of memory (enough to run BASIC), expandable to 8KB on board, or 64KB using expansion cards. A cassette interface was also available for the expansion slot, allowing for data storage and programming, such as easily loading the BASIC interpreter without having to program it in by hand.

The Apple I heralded a shift in personal computing. In the years prior, most computers were sold as kits, or assembled at a premium by the manufacturer. The purchase of a board that was completely tested and in working order led to “hassle-free” computing, helping spur personal computing towards a more mainstream consumer market. In 1977, the Commodore PET, TRS-80, and Apple II were released as assembled PCs, and hardware and software companies surged into a newly created market.

Apple Computers gave owners the option to trade in their Apple I for an Apple II, mainly to free Wozniak from his customer services duties as the only designer of the computer. With about only 200 made, and many removed from circulation due to the returns, Apple I’s have become a valuable collector’s item.

This spiral-bound manual has a green and white cover. It describes the use of the HP-55 programmable handheld electronic calculator. This version is dated December 1974. Compare with a slightly later version from February of 1975 (1980.0813.03). For an example of the calculator, see 1980.0813.01.

This spiral-bound manual has a green and white cover. It describes the use of the HP-55 programmable handheld electronic calculator. This version is dated February 1975. Compare with a slightly earlier version from December of 1974 (1980.0813.02). For an example of the calculator, see 1980.0813.01.

This fifty-nine-page manual describes the operation of the HP-45 handheld electronic calculator. For an example of the calculator, see 2004.3053.01. For another version of the manual, see 2004.3053.02.

This small orange spiral-bound notebook offers instructions on using the HP-65 calculator. It was received independent of a calculator. For an example of an HP-65, see 2011.0023.01. For other documentation on this calculator see 2012.3060.07 and 2012.3060.39.

This spiral-bound manual contains mathematics programs to be run on the HP-55 electronic calculator. According to the cover, it is a comprehensive guidebook, with “74 common programs in such areas as complex arithmetic and functions, linear algebra, trigonometry, geometry, business, and others.” It cost $10.00. A line on the back page reads in part: Rev C 5/75.

This section of the Daystrom 046 consists of the multiplexer, logic cabinets, and auxiliary memory. The 046 was manufactured by Daystrom's La Jolla division and was the company's first product utilizing transistors and core memory. Daystrom guaranteed a 99 percent availability, which was demonstrated at Louisiana Power & Light's Sterlington Plant. This 046 is the second purchased by Louisiana Power & Light. It was installed at the Little Gypsy Power Plant in 1961 in LaPlace, La., and was the first computer to control a power plant from startup to shutdown.

In the 1960s, when UCLA (the University of California at Los Angeles) purchased a commercial computer from IBM, students formed a club where they could share their knowledge of the new machines. At that time, data and programs were entered onto computers using punched cards like this one. The decoration of the card was up to the individual customer. This is a pink 80-column punch card for an IBM computer. Each column contains the digits from 0 to 9. The background of the card shows the head of a moose propped in front of a log. An open book lies on the left, and magnetic tape is in the mouth of the moose.
